That's what we do.View attachment 1046539 Shelia (one of my new Zealand rabbits) was on the verge of having a heat stroke! We notice it right in time! She is separated from her babies which didn't make matters better they were to hot and crouded in a small cage I moved her out and an ice back and ice cubes in her water she feel better!
